SPEED GOVERNOR.

Application filed May 11, 1925 Serial No. 29,445.

This invention relates to speed governors and particularly to speed governors for in ternal combustion engines. This application is a continuation in part of my prior applica- 5 tion Serial No. 747,389 filed November 1,

An object of this invention is to provide a speed governor for internal combustion engines, which will effectively regulate the speed of a motor by the current of air generated.

Another object of this invention is the pro duction for a speed governor for an internal combustion engine which will automatically regulate the air intake valve.

Another object of my invention is the production of a speed governor adaptable to motors of all types using a rotary fan for cooling purposes. The operation of the governor is such as to control the engine by the speed of the fan.

Another object of my invention is the production of a speed governor having an attachable means for regulating the action of the governor in accordance with the pressure of'the air current produced. by the rotary fan. 1

A further object of my invention is the production of a speed governor so constructed as to produce an air cushion to pre vent surges or vibrations, and thus an uneven operation of the engine to which it is applied, 7

Yet asfurther object of my invention is the production of a speed governor of the air intake control type, which maybe easily and quickly adjusted to any type .of motor car, truck, or traction engine now in use, and so connected by a control mechanism mounted upon the dash of such vehicles that it .will efficiently perform its intended function.

Still a further object of my invention is the production of a vspeed governor of the air intake control type, which will be highly efiicient in operation, yet of marked sim' plicity asv a whole and in respect to its component parts, so that its manufacture is economically facilitated both as regarding to parts and their assembly.

With these and other objects in view which may be incident to my improvements, the invention consists in theparts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements comprising my invention, may be varied in construction, pro

portions and arrangement, without departing from the spirit and scope ofthe'appended claims.

In order to make my invention more clearly understood, I have shown in the accompanying drawings means for carrying the same into practical effect without limiting the improvements in their useful applications to the particular constructions, which for the purpose of explanation, have been made the subject of illustration. 7

In the drawings forming part of this speciiication,

Figure 1 is a top plan view of an internal combustion engine with radiator and dash board, illustrating my inventionas applied,

Fig. 2 is a perspective view illustrating myimproved governor and dash regulating means,

Fig. 3 is a vertical sectional view partly broken away illustrating the means of mounting a movable vane,

Fig. t is an enlarged detailed perspective view. 7

Referring by numerals to the drawing, 1 represents an internal combustion engine such as is used in the manufacture or assembly of automobiles, trucks, and tractors. Mounted forward of the engine is a rotary fan 2 and a radiator 3, and to the rear of the engine is mounted a dash 40f usual or preferred type; v r

Mounted upon the radiator 3 at the top and bottom thereof, and to one side, are plates or brackets 5 and 6. The plates 5 and '6 support a curved wing 7 having shoulders 8 which are riveted on or otherwise secured tothe brackets.

The plate 7 is curved inward toward the motor with its free end bent back, as shown at 9, in order to give strength and rigidity thereto.

Formed upon the plate 5, on the lower face thereof is a socket 10 anddiametrically opposite the socket 10 in the plate 6 is mounted a bearing 11 having threaded thereupon oppositely disposed taps 12 and 13, by which. thebearing may be adjusted. The bearing 11 is provided at its upper end with a socket 14 in alignment with the socket 10. The low-er end' of the bearing is proill) vided with a slot for the reception of a screw driver or other implement suitable to make adjustment.

Mounted between the sockets 10 and 14% 1s a shaft 16 secured to which is a curved vane 1'? of the same general contouras the wing 7 but smaller in proportion. The vane 17 is secured to the shaft 16 by folding one edge around the shaft, as shown at 18, to which it is secured by rivets orin any other desirable manner. The free end of the vane is bent back upon itself as shown at 19, in order to impart strength and rigidity thereto.

The wing 7 and the vane 17 are in a spaced relation with respect to each other, and are of the same general contour. The vane 1?, however, is smaller, hence, when current of air is directed upon the vane the same current plays against the wing 7 which owing to its articular formation pro duces a backcui out, thereby forn'iing a cushion against which the vane 17 presses. The actionis such as to insure a smooth control and to eliminate sudden surges when the load is increased or diminished.

Mounted upon the upper end of the shaft 16 is a sleeve or collar 20' locked or keyed to a shaft 16 in any desi able manner. Integral with the collar 20 is an arm 21 the free end of. which is apertured to receive the end of a rod 22 the same being held therein by a pin 23. The other end of. the rod 22 engages an aperture 24L in an arm 25, mounted upon a shaft 26-. The opposite end of the shaft 26 is enlarged and slotted as shown at 2'7 forengagement with an air inlet valve.

The shaft 26, is support-ed by an arm 28' bolted to the base of the engine, and a plate 29 adapted to be bolted to the air intake valve.

Mounted on the; dash 4; and extending for ward beyond the motori's a shaft 30 adapted tooperate by a hand wheel 31. The rod 30 is supported upon its forward end by a plate or bracket 32. Mounted upon the forward end of' the rod 30 and bearing against thebracket 32 is a washer 33 held in place by a pin Set. The free end of the, rod 30 is provided with a lug 35 attached to which is a chain 36 connected to a spiral spring 37 which in turn is connected to an, arm 25. itwill be observed that by operating the hand? wheel 31' mounted on the dash, the tension of the spring 37 can be regulated. The tension of the spring tends to limit the movement of the vane.

' While I have shown and described" the preferred embodiment of. my invention, I wish-it to be understood thatlj do not confine-myself to the precise details of. construction herein set forth, by way of'illustration,
